Question 1

Monohybrid across

Answer 1

A genetic cross between two individuals involving the inheritance of a single gene with two alleles

Question 2

Phenotype

Answer 2

The observable characteristic of an organism resulting from the interactions of its genotype and environment

Question 3

Genotype

Answer 3

The genetic makeup of an organism describing the alleles present for a particular gene

Question 4

Genes

Answer 4

A segment of DNA that quotes for a specific protein or functional RNA influencing a particular characteristic

Question 5

Alleles

Answer 5

Different form or variation of gene that occupy the same locus on homologous chromosomes

Question 6

Homozygote

Answer 6

An individual with two identical alleles for a particular gene AA or aa

Question 7

Heterozygote

Answer 7

An individual with two different alleles for a particular gene Aa

Question 8

Dominant

Answer 8

And Ali that is expressed in the phenotype, even when only one copy is present

Question 9

Recessive

Answer 9

And Ali, that is only expressed in the phenotype when two copies are present (homologous state)

Question 10

True breeding

Answer 10

Organisms that when self crossed produced offspring with the same phenotype for a particular characteristics over several generations, they are homozygous

Question 11

Test cross

Answer 11

A genetic cross between an organism with an unknown genotype and a homozygous recessive organism to determine the genotype of the unknown organism

Question 12

Codominant

Answer 12

A situation we are both alleles in a heterozygote are fully expressed in the phenotype resulting in a distinct expression of both characteristics
